Comment on the summary: The overall signal for near normal temps was correct. PPN not so good although hinted at SE being drier.
1. Russia: Hinted at colder in NW but otherwise temp and rain distribution not a help.
2. USA - CFS2 : Overall near normal temp OK but month by month detail lacking. PPN data 26th good overall distribtion and fairly good month by month detail other runs not so good.
3. UKMO Contingency: Season and March temps OK. March ppn good idea of split but season not correct.
4. UKMO :Temp good idea of colder in N and W but detail not good. PPN good with NW to be above but other detail not so good.
5. USA - IRI : Temps as normal overly warm but PPN indication of drier in SE
6. KMA APCC : Temp fair PPN poor
7. JMA : Temp and PPN not a help
8. NMME : not good for season temp and PPN BUT month by month got the idea of Apr being milder than March or May. Month by month PPN not a help.
9. IMME - not a help.
12. BCC - not a help incorrect distribution of temp and ppn.
11. Brazil - not a help
12. NASA - seaon temp OK but ppn not good. Month by month detail not good.

Summary: Comment 200115 was OK both with temp and ppn. Models no one stands out as being better. NMME cooler to W indication and hint at warmer in E of England was fair.

DATA available in December 2014 for Mar Apr May 2015

CFS2 graphics got idea of APR being milder than Mar or May but not the colder May. NASA output was probably the best for season but month by month detail incorrect.
